Japanese motorcycles moving into forced induction

While turbocharging and supercharging may be nothing new in the automotive industry, motorcycle engines are almost always naturally aspirated. But even that's beginning to change. At the Tokyo Motor Show last week, two major Japanese companies showed off new forced-induction motorbike engines.
Kawasaki rolled in with a supercharged four-cylinder motorbike engine. It offered little in the way of details, disclosing only that the turbine blades were developed in-house to withstand the heat and vibration of spooling up at motorbike speeds.
Suzuki is taking a different approach, however. Its Recursion concept bike packs a turbocharged 588cc two-cylinder engine with a turbocharger and intercooler. The compact package churns out just under 100 horsepower and 74 pound-feet of torque, packaged into a motorbike that weighs just 384 pounds dry.

Suzuki previews e-Survivor concept, the cutest ute yet

If you've ever thought of Suzuki as a whimsical manufacturer of small or smallish vehicles, you're going to like what the manufacturer plans to show at the upcoming 45 th Tokyo Motor Show. The e-Survivor Concept reimagines the classic Suzuki jeep as an all-electric vehicle, and it's filled with interesting styling cues both retro and futuristic. The e-Survivor is not only lightweight in construction, it also looks like it, with vestigial wheelarches and see-through doors. The electric motors are housed in the wheels, leaving the ladder-frame construction able to be as skinny as possible. The dashboard houses large screens showing infotainment controls, navigation settings and the vehicle itself, and there are rear-view cameras in place of mirrors. According to the manufacturer, the e-Survivor is a compact SUV of "the next age," which could even hint of an electric 4x4 being the way for Suzuki to survive in this century — or in its second century: the company is 100 years old in 2020, and its concepts show what Suzuki sees beyond that. Perhaps something from the e-Survivor will make production after 2020; independent wheel-mounted electric motors would certainly suit a small, light SUV. Other exhibits are the "tall miniwagon" Spacia Concept, the XBEE crossover available in several different guises, the friendly-looking Carry Open-Air Market Concept and a "neo-retro styled" SV650X bike.

Suzuki Jimny gets confused by American guardrails

The reborn Suzuki Jimny 4x4 has faced some crosswinds in the time it's been on the market: It earned only three stars in its Euro NCAP test due to a badly-inflating driver airbag and troubles with pedestrian protection. The automatic emergency braking function also had some issues in NCAP testing, but now the Jimny's AEB system is facing an another problem — it appears to be confused by guardrails. Two German-market Jimnys had been shipped to Los Angeles for the World Car of the Year testing, Australian journalists found that on some corners of the California test route, the AEB was seemingly triggered by a guardrail in a curve in the road. The problem was found with both Jimnys, and Suzuki's Jimny chief engineer was present to look into the matter; later, Suzuki engineers were able to replicate the glitch with these particular vehicles on the same road. While U.S. sales of the Jimny are extremely unlikely, test data acquired on American roads still seems to be highly valuable for Suzuki, as tests in Japan could not replicate the problem. It appears the road condition, tilt angle, curve aspects and vehicle speed all conspired to puzzle the AEB system, which is now being evaluated for a software or calibration change. The jerky correction by the electronic stability program, audible on the CarAdvice video, happened at 45-55 mph, which is not overly fast for even the narrow and tall Jimny — it is possible that the AEB mistook the guardrail for another car. Suzuki stated: "There is a possibility that the (stability control) is instantaneously switched on (by) reacting to the vehicle sway when departing the S-shaped curve — and then consecutively switches on because the vehicle is circling the curve at high speeds. [...] The intervention of the stability control may give a sense of discomfort to the driver but is not an event that would disturb the vehicle's direction of movement." The driver safety assists are a good addition to the Jimny, of course, given that the 1980s second-generation truck was the subject of a beef between Consumer Reports and Suzuki North America due to its reported tippiness in corners.
